Its specific goal is the measurement of image velocity (or optical  flow), the projection of 3-D object motion onto the 2-D image plane.  \u003cbr\u003e  The formulation of the problem emphasizes the geometric and  photometric properties of image formation, and the occurrence of  multiple image velocities caused, for example, by specular  reflections, shadows, or transparency. The method proposed for  measuring image velocity is based on the phase behavior in the output  of velocity-tuned filters. Extensive experimental work is used to show  that phase can be a reliable source of pure image translation, small  geometric deformation, smooth contrast variations, and multiple local  velocities. Extensive theorectical analysis is used to explain the  robustness of phase with respect to deviations from image translation,  and to detect situations in which phase becomes unstable. The results  indicate that optical flow may be extracted reliably for computing  egomotion and structure from motion. \u003cbr\u003e  The monograph also contains a review of other techniques and frequency  analysis applied to image sequences, and it discusses the closely  related topics of zero-crossing tracking, gradient-based methods, and  the measurement of binocular disparity. The work is relevant to those  studying machine vision and visual perception. \u003cbr\u003e\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2012-09-30\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9781461366232\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-1-4615-3648-2\u003c\/p\u003e \u003cp\u003eDimensions: 235.0cm x155.0cm\u003c\/p\u003e \u003cp\u003ePages: 203.0\u003c\/p\u003e ","brand":"Springer US","offers":[{"title":"Default Title","offer_id":44407998251148,"sku":"9781461366232","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9781461366232.jpg?v=1767147410","url":"https:\/\/lateknightbooks.com\/products\/9781461366232","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
